Where are nutrients absorbed into the blood through the walls of?
It passes through the wall of the digestive system, then into the blood.
How does the digestive system help estract energy from food?
the digestive system breaks down the food, anything which is vital to the body is passed through the intestine walls, ( im not sure which, i believe it is small ). The nutrients are passed through the intestine walls and into the blood stream
How do nutrients in digestive system reach the blood stream?
Through millions of microscopic villosity placed on the walls of the small intestine.
What are the wave of muscle contractions that pushes food through the digestive system?
Smooth muscle in the walls of the digestive tract contract and form a movement called peristalsis.
What is the process of pushing food through you body?
The food gets pushed through your digestive system by contaction in a ring of the smooth muscle in the walls of the various organs of the digestive tract (oesophagus, stomach, small and large intestine) and this is called peristaltism.
What does the intestinal fluke eat?
They feed off the inner walls of the digestive system.
Compare and contrast the role of the villi in the digestive system with the role of the alveoli in the respiratory system?
they are very similar, both have: thin walls through which particles can pass consist of tiny projections occurs in huge numbers
Which two actions help to propel a bolus of food through the digestive tract?
Propulsion is the movement of food down the esophagus and peristalsis is the contractions in the stomach walls that moves food through the digestive tract.
How do smooth muscles and sphincters keep food moving in one direction throughout the digestive system?
by peristalsis which is the rhythmic, involuntary contraction of the smooth muscles in the walls of digestive organs.
Does fiber help food particles travel through the digestive system?
yes. fiber provide bulk to the food moving along the alimentary canal. It helps in peristalsis occurring in the walls of gut. I think its enough :)
Where does digestion start in alimentary canal?
digestion starts in your mouth it is called cephalic phase. Almost all animals have a tube-type digestive system in which food enters the mouth, passes through a long tube, and exits as feces (poop) through the anus. The smooth muscle in the walls of the tube-shaped digestive organs rhythmically and efficiently moves the food through the system, where it is broken down into tiny absorbable atoms and molecules
How is food digested absorbed and transported to the cells?
it is absorbed through the walls of the small intestine into the bloodstream.
